i'm gonna go with the Type R manifold and then buy a Type R intake. Too bad the Type R intakes are so expenisve. The reason i'm deciding to do it that way is because i know someone that has a civic hatch with a b18c1 in it and he said one of the best gains he got was with the skunk2 manifold and he has the skunk 2 intake. But he said go with the Type R manifold because its just as good or better. Too bad now i gotta get rid of my AEM CAI for one that will fit to the Type R one.
